CHARACTERISTICS ANALYSES OF ENERGY CONVERSION AND REUSE INTERACTION SYSTEM

Active seismic response control system by making use of an energy conversion in dampers Part 2

Abstract

 We have reported an active seismic response control system by making use of an energy conversion in damping devices³⁾. In this paper, we propose a system where energy conversion and reuse are interacted, we call it ‘interaction system’ here, and evaluate its characteristics through seismic response analyses. In the ‘interaction system’, responses are drastically reduced by the control gain where energy input and output are balanced. In addition, in comparison with an ‘independent system’ shown in Part 1³⁾, the ‘interaction system’ shows the similar response reduction effect by this control gain. The damping force and velocity of the passive devices are about 60% of the ‘independent system’, and the control force and velocity of active devices are equivalent. The ‘interaction system’ shows a possibility that it can construct the total system compactly, compared with the ‘independent system’. The proposed system can realize the active seismic response control system against large earthquakes where its application in the actual stage is supposed to be difficult.
